AST18 Deck-Mounted Spout

Heightened Expression, Enhanced Usability

The AST18 mixer, featuring a 370 mm tall spout, is conceived as a sculptural yet highly functional element, inspired by the unmistakable dual symbolism of the ASTA stem and a microphone silhouette. This product introduces verticality to the ASTA collection, giving more freedom in water delivery and accommodating broader basin typologies. Its removable and adjustable neck, connected by a colored flexible tube, brings intuitive handling and movement into daily rituals.

The tube, available in aqua green, cobalt blue, anthracite grey, and white, acts as both a tactile feature and a conduit of personality. Engineered for versatility, it can be detached or repositioned to suit the exact user need, offering new ways to interact with the tapware.

Sustainable Strength in Every Molecule

Made entirely from AISI 316L stainless steel, AST18 embodies structural integrity combined with environmental mindfulness. The low-carbon content of this steel enhances its anti-corrosive properties, especially in marine or sulphurous conditions. Through a cold-forming process, the natural strength and hygiene of the material are preserved without applying galvanic coatings. This not only ensures a toxin-free, fully recyclable finish, but also aligns with CEA’s core values of ecological responsibility and long-term sustainability.

Surface Treatments Beyond the Ordinary

AST18 is available in both satin and polished mechanical finishes, as well as CEA’s sophisticated SPECIAL FINISHES: Black Diamond, Bronze, Copper, and Light Gold. Each of these coatings is applied using a plasma vacuum process that deposits zirconium-graphite compounds onto the steel’s surface at high density. The resulting finish is not only elegant but also exceptionally hard-wearing, offering:

• Greater resistance to scratches and detergents

• Protection against sea air and harsh cleaning products

• Reduced mineral adhesion, particularly in the Black Diamond version, where the surface remains cleaner longer due to a self-lubricating mechanism

CEA finishes are biocompatible, chemical-free, and manufactured with precision for enduring brilliance.

Flexible Silicone: A Technical Marvel

The medical-grade silicone used for AST18’s flexible tube offers notable benefits beyond aesthetics. Designed to resist thermal extremes, oxidation, and tearing, this material delivers extended durability in indoor and outdoor environments alike. It prevents limescale build-up, maintains its color over time, and remains easy to clean—ideal for wet zones. Unlike rigid metal hoses, the silicone tube provides a more natural handling experience, making it especially suited for progressive and frequent use.

Maintenance

To preserve the AST18 mixer in pristine condition, regular cleaning using products intended for stainless steel will always be necessary. After each use or cleaning session, rinsing and drying the surface will help avoid stains and prevent the accumulation of mineral residue. The use of aggressive chemicals—such as chlorides, bleach, or acids—must be avoided, as they may cause irreversible surface degradation. Instead, mild agents with a neutral pH are preferable. If deeper cleaning is needed, a diluted solution of sodium carbonate or isopropyl alcohol may be used sparingly on metallic surfaces only. These non-toxic options maintain both hygiene and finish integrity. Contact with fumes or liquids from products containing ammonia or hydrochloric acid should be strictly avoided, as should abrasive scrubbers, powders, or brushes that could dull or scratch satin and polished surfaces. For long-term protection and reduced internal scale buildup, it is strongly recommended to install an effective water filtration and softening system, which will extend both function and finish for years to come.
